What problems should be paid attention to in the use of carbon enhancers for casting:

1, choose the right carburizing agent for their own furnace: want to use a good carburizing agent in casting should choose the type of good carburizing agent, because different carburizing agents are often applicable to the smelting furnace is also very different, before purchasing the carburizing agent to fully understand their own furnace to use that type of carburizer;

2, the choice of nitrogen content meets the requirements of the carburizing agent: in general, in the casting should choose a low nitrogen content of the carburizer, which will ensure that the harmful substances are minimized, the content of titanium in the molten iron is very low, will not consume a lot of nitrogen, which is easy because of the increase in nitrogen content and a large number of stomatals, air shrinkage and other defects;

3, the choice of better graphitization carburizing agent: casting should try to choose a better graphitization carburizer, otherwise it will lead to low absorption rate, slow, slag, there will be harmful elements affecting the quality of molten iron;

4, the appropriate time to put in the carburizer: casting should pay attention to the addition time of the carburizer, generally can be added in the early stage of casting, the middle stage, the later stage can be added, can also be added with scrap steel, in the later stage can also play a role in pretreatment, can increase the graphite core.
